Auto ISO Sensitivity Control
If On is selected for ISO sensitivity settings Auto ISO sensitivity control in the

not be achieved at the value selected by the user (ISO sensitivity is adjusted 
appropriately when the flash is used).

ISO sensitivity settings in the shooting 
menu.

ISO sensitivity will remain fixed at the value 
selected by the user).

Adjust settings.
The maximum value for auto ISO sensitivity 
can be selected using Maximum sensitivity 
(the minimum value for auto ISO sensitivity 
is automatically set to ISO 100; note that if 
the value selected for Maximum sensitivity 
is lower than the value currently selected for ISO sensitivity, the value selected 
for Maximum sensitivity will be used). In modes P and A, sensitivity will only 
be adjusted if underexposure would result at the shutter speed selected for 
Minimum shutter speed (
1
/
2000
–1 s, or Auto; in modes S and M, ISO sensitivity 
will be adjusted for optimal exposure at the shutter speed selected by the user). 
If Auto (available only with CPU lenses; equivalent to 
1
/
30
s when a non-CPU 
lens is used) is selected, the camera will choose the minimum shutter speed 
based on the focal length of the lens (auto shutter-speed selection can be fine-
tuned by highlighting Auto and pressing 
2; for example, even faster values 
than those usually selected automatically by the camera can be used with 
telephoto lenses to reduce blur). Shutter speeds slower than the minimum 
value may be used if optimum exposure can not be achieved at the ISO 
sensitivity value selected for Maximum sensitivity. Press 
J to exit when 
settings are complete.
